T 0 all whom t may concern.'

Be it known that I, LoUIs S. GRUnn, a citizen of the United States, anda resident of Arnold, in the county of lVest-moreland and State ofPennsylvania, have invented a new and useful Improvement in W'indows, ofwhich the following is a specification.

The objects of the invent-ion are to provide a window construction whichwill be durable, compact, convenient to clean and easy to operate; whichcan be easily repaired whenever necessary; and which can be swung to aposition to permit thefull space occupied by the window to be utilized.

. Further objects are to provide convenient means for balancing thesashes and for locking themv into any desired position; to providescreens forming a part of the window construction proper which can beeasily attached to or released from the Sashes and which will becompletely hidden when not in use; to prevent the leakage of rain ormelted snow, which trickles down the exterior of the window, into theinterior of the lower sill; and to produce a window in which .all of theoperating mechanism therefor is protected and is out of sight so as topresent a pleasing appearance.

The window illustrated as the preferred embodiment of the invention isconstructed entirely of metal, the outer casing, the main frame and sashframes being formed of suitably shaped pieces of sheet metal attachedtogether by any well known means. These parts which are' exposed arepreferably made of some lmetal which is capable of resisting theelements as for example, sheet copper. The particular material used,however, forms no part of the invention as any suitable material may beused and it is not intended to limit the invention beyond thatparticularly pointed out in subsequent claims. l

In the accompanying drawings forming a part of this specification, 'thesame reference characters denote corresponding elements through theseveral views in which Fig. 1 is an elevation showing the windowcompletely assembled, lthe screens and operating mechanism beingindicated in dotted lines; Fig. 2 a vertical sectional view on lineI'L-II, Fig. 1; Fig. 3 a transverse vertical "sectional view with partsshown in elevation on linel III-III of Fig. 1; Figs.

4 and 'fragnientary sectional views with partsy in elevation showing`details, Fig. 6 a ltransverse horizontal sectional view on line Vl-Vl ofFig. 1; Fig. 7 an enlargedy f to Fig. 7 showing a modified-form of 'theactuating mechanism; Fig. 9 a section" also showing theoperatingmechanism taken on line I'x-JX'of'Fig. 7; and Fig. 10 is afragmentarydetail view showing therelative positioning of the partsofthe locking device illustrated inv Fig. 4 when operatively engaged. l

The window comprises the'ou'ter casing 1 so shaped as toprovide a recess2 in which is hingedly supported at 3 and 8 the. main frame 4, in whichthe vertically slidable sashesV and 6 vof a well .knowntype aremounted.l The outer casing 1 is formed at its top with a dependingportion7 and' atl its sides with inwardly projecting portions 8 ywhichact to form a limiting abutment or stop for the frame 4 when said frame,occuf pies its normal position as illustrated lin Fig. 1, and `in fulllines` in Fig. 6. The

frame 4, however, may be 'swung outwardly to the position indicated by'thev dotted lines in Fig. 6 so as to render it possible yto utilize theentire opening through the casing 1. rl`his is found to be of particularimportance in oiiice buildings and similar structures fory the admissionof large safes or pieces of furniture. The window is also swung to its.

dotted line position for the purpose of cleaning the exterior thereof.

At one side of frame 4 are mounted the spirally grooved shafts 9 -and 10journalled at their upper ends in a bearing Vbracket 11 and at theirlower ends in a pair of spaced bearing blocks 12 and 13, respectively. lThe shafts have'attached n ear their lower ends y pinions 14, 14 meshingwith the respective pinions 15, 15', both of the latter encircling a rod16 slidable in an aperture 17 in block 12 and a recess 18 in block 13.intermediate Y its ends, the rod 16 carries a pin 19 which is adapted tolit into the grooves 20, 21y in the adjacent faces of the respectivepinions 15, 15 for a purpose to be presently explained. l In Fig. 7, thepinions lyand l5 are shown as positioned adjacent each other leaving buta small space between their abutting faces, while in Fig. 8 isillustrated a modified form in which the pinions are spaced apart by theabutting arcuate bosses the Width ot the open space indicated at 19being slightly greater than the Width ot the pin 19. The length of thepin 19 in this form is less than the distance betvveen diametrica-llyopposed portions of the bosses so as to freely rotate Within the space19 Without touching the same. rEhe construction in Fig. 8 permits theshitting of the rod and pin 19 to engage either pinion without firstbringing the grooves in the faces of the same into aligninenhthe pin 19being simply projected into the space 19 and turned therein until itcomes into a position to align with the groove into which it is to beitorced.

The bearing block 12 is equipped with a pin 22 provided with a round-edend springpressed into either of tivo series ot shallow impressi-ons 23formed on the rod 16 and a similar pin 24 fits into the depressions 25in the tace of pinion 15, the bloclr 13 also being similarly equipped asshovvnat 25 tor the purpose of slightly retarding free rotation of thepinions. The end oi" rod 16 has a handle 2T attached thereto to whichaccess inay be had through lthe closure Q8 in the trame rlhe openposition ot closure 28 is indicated by dotted lines in Figs. T3y and 7.

Sliding upon the shafts 9 and 19 are the respective nuts Q9, BO, eachnut being provided with an internal tongue or similar device 'forengaging the spiral groove-ot the shaft. The nut 29 is connected to theloiver sash and the nut 30 to the upper sh by an extension 30 or 31which is pre ably tached adjacent the upper end oi the sash. Theseextensions project through slots provided in the sash guiding grooves.

Rotatably mounted in the upper and loiver ends oi the trame 4 springrollers 83 and 34. Upon each roller is -Wound a flexible screen 55 suchas is comin-only used for excluding insects from doors and ivindoivs,Whose width is slightly greater than the Width oi the Window sash sothat the edges thereof project Within slots provided in the sashgrooves, the right hand edge viewed in Fig. 1 riding in the same slotthrough which the extension attached to nut 30 or 31 projects aspreviously discribe'd. The rollers normally Wind and retract the screensinto the position illustrated in Fig. 1, the roller 33 cooperatingyvvith the upper sash and the roller 34 with the lower sash in a mannerto be presently described.

Each ot the rollers is removably mounted and since the construction usedfor this purpose is substantially the saine Jrior both rollers only thatused in connection 'vvitn one need be described in detail. Si pintle onone end of the roller rides in an aperture in the bracket 37 rvhilethesquared exten sion 88 at its other end is retained in the slot 39 inbracket 11 by a latch 40 pivoted at 41 and locked as shown at 42. hemeans for retaining the squared extension on the lower roller differsfrom that of the upper one merely in extending the slot or recess in thebracket upwardly and providing an angular offset adjacent its upperextremity, and in pivoting the latch so that the normal position of itsaxis is vertical instead ot horizontal, as clearly shown in Fig. 3.

The screens are prevented from being completely Wound upon the springrollers by catches 43 fastened to the tree end of each screen whichprojects through a slot in the sill or lintel for that purpose, thecatches being of such dimensions as to prevent their passing through thesaid slot. The catch acts as a limiting means for the screen and is heldiirmly in position by the tension of the roller for engagement with theof the spring-pressed sliding bolt 44 located in the sash of the Window.

For the purpose of locking the sashes in various positions as maybedesired, several means are employed. n the form illustrated in Fig. 3,shafts 9 and 10 `are provided with a series of recesses 45 With whichthe catches 46 carried by the nuts 29 and 30 co act. The main body otthe catch 46 is Jfornied of spring metal and its bent end eX- tendsthrough an opening in the sliding nut so as to enter one of the severalrecesses 45 to lock the saine at any desired height. ln the normaloperation of the device, the end of the catch is Withdrawn and the catchmoved about its point of attachment k47 as a pivot out ot register withthe opening through the nut.

in Fig. 4, the nut 29 is held at any desired position by the slidinglock 48, the` lock being pivotally and .slidably mounted upon a rod 49located at the side of the shaft 9. rlihe main body of the lock 48 isprovided with a pair of spaced fingers 50 Iadapted to straddle the nutQ9 and to be swung into the position indicated in Fig. 4, the lock beingpivotally swung disengaging the `nut when not desired. By sliding thelock up or down upon the rod 49, the saine may be positioned to lock thenut and attached sash :in any desired position. Due to the loose #lit ofthe lock upon the rod any pressure upon either linger 5() tends to torcethe lock askeiv resulting in a binding action eiectively holding thesaine againstvertical movement.

In some instances, it has been found highly desirable to equip theWindow rwith means for preventing the entrance of unauthorized personssuch as burglars. Such means as shown in Fig. 5, 51 being a series oispaced metal rods or bars projectingupivardly -through the lower sillwhich are attached to the lower end of the sash 6 thus forming a barrierwhen the sash-is raised.

In order to prevent therain-or melted snow which trickles down theexterior of the panes from entering the hollow sill construction andcausing damage, and also to prevent the same collecting upon the sill,the sill 52 is inclined as clearly shown in Fig. 2 so t-hat any liquidco-llecting thereon will be readily discharged, the grooves 53 beingprovided to facilitate such action.

For holding the window frame 4 in its operative position in the outercasing a combination latch and lock 54 is provided as shown in Fig. 1,the portion 55 coacting with the portion 56 mounted upon the casing 1 inthe usual manner. If it is desired to prevent opening of the frame 4,the catch 54 may be locked by inserting a key through the key slot 57.

The operation of the device is -as follows: Vith the form of actuatingmechanism shown in Fig. 7, in order to shift the pin 19 from the groovesin either pinion 15, 15, it is first necessary to bring the oppositelyfacing grooves 20 and 21 into alignment, in which position of the parts,the pin 19 may be selectively engaged with either pinion bylongitudinally. moving the rod 16. Subsequent rotation of the rod willrotate the pinion. The turning of pinion 15 or 15 results in therotation of the corresponding shaft 9 or 10 and the sliding nut and itssash will be moved due to the cooperation between the nut and spiralgroove in the shaft. Turning in one direction will cause the sash toascend while turning in the opposite direction will obviously cause itto descend. By positioning the pin 19 so as to partially project intoboth grooves 20 and 21 both sashes may be moved simultaneously ifdesired, or a single'v sash may be moved at a time by projecting the pin19 entirely within the groove of a single pinion, the disengaged pinionbeing prevented from turning, and allowing the sash to lower under theiniiuence of gravity, by the spring pressed pins 24 or 26 as the casemay be, the tension of the latter means not being sufficient, however,to prevent the sash being moved by force, if desired.

1With the form shown in Fig. 8, the pin 19 may be projected into thegrooves in either pinion, as desired, as previously described, andalthough this form is not capable of causing simultaneous actuation ofthe sashes, it makes possible the shifting of said pin from engagementwith one pinion into engagement with the other regardless of therelative position of the other and without first bringing the oppositegrooves of the two pinions 15 and 15 into alignment.

When the sashes have been moved to the positions desired, they may besecurely locked at such points by releasing the catch 54, swinging theframe 4 inwardly on its hinges to the dotted line position in Fig. 6 andsetting the locking means 46-47 Fig. 3,

or 48-50 Fig. 4, as previously explained,

when the frame is again swung into and locked in the position shown infull lines in Fig. 6 or in Fig. 1.

At night, it is intended to position and ing the bolt 44 from the catch43. When the sash is moved to its full closed position, and the bolt 44is spring-pressed to the left, Fig. 1, so as to bring its end intoposition to be contacted by the curved portion 43 of the catch, the boltwill engage the slot of the catch thus locking the screen to the windowsash. Either a raising or lowering'of the sash when the screen i-s thusattached will cause the screen to be moved therewith thus closing thespace between the sash and frame. The screen may be released regardlessof the position of the sa-sh by simply drawing the bolt 44 to the rightso as to disengage the catch 43 when the tension of the spring rollerwill retract the screen to the position indicated in Fig. 1.
